SMX: Secure Virtual Machine Technology - bit6 is for SMX, but [it's
meaning](https://en.wikipedia.org/wiki/CPUID) is Safer Mode Extensions
(part of TXT). Not Secure Virtual Machine Technology (which is already

- Modified builtin slirp API to reduce differences.
- NOTE: IPv6 support present in libslirp is not yet enabled (needs more testing).

Fix checking Android platform with __ANDROID__ macro (#299)
